Asset data glossary

A

Age

Years an asset has been in service, counted from its install date.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Asset hierarchy

The agreed tree that sorts everything an organization owns into levels and classes, so each kind of asset is named and described once.Read more: What is an asset hierarchy?.

Availability

The share of time an asset is able to do its job when it is needed, once planned and unplanned downtime are taken out.Used in Oil and Gas and Aviation.

C

Capital renewal program

The funded list of assets to rehabilitate or replace over the coming years, and the order they come in.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Condition score

A graded reading of an asset’s physical state taken at inspection, usually on a fixed scale such as 1 to 5.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Consequence of failure

What a failure would cost or cause (safety, service, environmental and financial harm), judged separately from how likely it is.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Corrective maintenance

Repair work done after a fault or failure has been found.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Current state

How well a data point is captured today: captured and trusted, captured but needs cleanup, partly captured or not captured.Read more: Data readiness for analytics.

Current system

The system a data point is collected and saved in today. Strata records it by name; left blank, it means not yet assigned.Read more: Hierarchy, EAM, CMMS and GIS.

D

Design standards

The decision on what new assets must meet: materials, sizing, approved products and how they are built.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Desired system

The system a data point should live in. Left blank, it means it stays where it is; when it differs from the current system, it is on the migration list.Read more: Hierarchy, EAM, CMMS and GIS.

Dissolved gas analysis

A lab test of the gases dissolved in a transformer’s oil, whose mix points to internal faults such as overheating or arcing.Used in Electric distribution.

E

Expected useful life

How long a class of asset is expected to last in service, from its design or from experience with similar assets.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

F

Foreign object debris reports

Records of loose items found on airfield pavement that can damage aircraft, counted so patterns show.Used in Aviation.

Fracture-critical

A bridge member whose failure could bring down the bridge or part of it, because no other path carries the load.Used in Bridge.

Friction level

How much grip a runway surface gives tires, tested to decide when it needs treatment.Used in Aviation.

H

High consequence area

A place defined in US pipeline safety rules where a release would do the most harm, such as near dense population; it raises inspection requirements.Used in Oil and Gas.

I

Inspection frequency

How often each kind of asset is inspected, set from its risk and its condition.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Install date

The date an asset went into service; the starting point for its age.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

L

Lifecycle stage

A phase of an asset’s life, from planning to disposal. Strata uses Plan, Create, Operate, Maintain, Renew and Dispose.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Likelihood of failure

How probable a failure is in a given period, judged from age, condition and failure history.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

M

Maintenance strategy

The choice of how a class of asset is maintained: run to failure, on a schedule, by condition or by prediction.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Maximum allowable operating pressure (MAOP)

The highest pressure a pipeline may be run at, set by its design, its pressure tests and its condition.Used in Gas distribution and Oil and Gas.

N

Needs assessment

The planning step where gaps in condition, capacity or service are found before money is committed.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Nominal diameter

The standard size label of a pipe, which can differ a little from its true internal diameter.Used in Gas distribution and Water and Wastewater.

P

Pavement condition index

A 0 to 100 score of a pavement’s surface condition from a survey of visible distress; higher is better.Used in Transportation and Aviation.

PCOAR

Plan, Construct, Operate, Analyze, Retire: a lifecycle framing used in the gas industry. Strata’s stages are a plain-English version of it.Read more: Lifecycle stages and PCOAR.

Pipe-to-soil potential

A voltage reading between a buried steel pipe and the surrounding soil, used to check that its corrosion protection is working.Used in Gas distribution.

Planned rehab / replace year

The year an asset is scheduled for rehabilitation or replacement in the capital plan.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

PM / CM ratio

Planned preventive maintenance work set against corrective work done after failures: a measure of how much maintenance is planned.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Preventive maintenance

Planned work done on a schedule or by condition to head off failure, such as inspection, lubrication or exercising valves.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

R

Rated capacity

The most an asset is designed to deliver, such as flow, load or power, as stated by its designer or maker.Used in Electric distribution, Water and Wastewater and Data Center.

Remaining useful life

How many more years an asset is expected to serve: its expected useful life less its age, adjusted for condition.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Remaining wall thickness

The metal left in a pipe or vessel wall after corrosion, measured at inspection and compared with the minimum allowed.Used in Oil and Gas.

Repair, rehabilitate or replace

The choice between fixing an asset, restoring it to near-new condition and replacing it, given its condition and cost.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Replacement cost

What it would cost today to replace an asset with an equivalent one; the figure renewal budgets are built from.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Retroreflectivity

How well a sign or road marking returns headlight beams to the driver. It fades with age and sets when signs are replaced.Used in Transportation.

Risk ranking

The decision on which assets carry the most risk and so come first for inspection, repair or renewal.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Risk score

Likelihood of failure and consequence of failure combined into one number, used to put assets in order.In every template, on the root class. For example, Water and Wastewater and Gas distribution; all templates.

Run hours

Hours an engine, motor or pump has operated: a better measure of wear than calendar age for rotating equipment.Used in Water and Wastewater and Data Center.

S

Scour critical

A bridge whose foundations are at risk of being undermined by flowing water washing away the soil around them.Used in Bridge.

Section loss

Reduction in the cross-section of a structural member from corrosion or wear, which makes it weaker.Used in Bridge.

Structural defect grade

A grade for a sewer pipe’s physical defects, such as cracks and collapse, taken from a camera inspection.Used in Water and Wastewater.

W

Wire-to-water efficiency

A pump’s overall efficiency: the power delivered to the water divided by the electrical power drawn from the supply.Used in Water and Wastewater.
